Hialeah, Florida, homicide detectives have charged an elderly man with the shooting death of his sister-in-law.

Two bodies were found inside the home of 78-year-old Angel Dominguez on the 200 block of W 45th Street Friday afternoon. Police say Dominguez shot and killed his 80-year-old sister-in-law Hidelsia Echemendia, who was visiting from Cuba.

Dominguez's wife, 87-year-old Blesilda, was also found dead in the home. Police have not yet released her cause of death, but say there were no visible signs of trauma. A neighbor told NBC 6 that the woman had a heart attack after finding out about the shooting.

Several neighbors said they heard shots from the area of the home.

“I came out of the house. I was helping my grandpa load some things on the truck,” said neighbor Alexis Espinosa. “We heard a gunshot, but we didn’t hear nothing else.”
